Write the equation in POINT SLOPE form:

( 4, 2); m = 3

• y - 2 = 3( x - 4)

• y - 2 = 3( x + 4)

• y - 4 = 3( x - 2)

• y + 2 = 3( x + 4)

Write the equation in POINT SLOPE form:

( -2, 4); m = 1/2

• y - 4 = 1/2( x + 2)

• y - 2 = 1/2( x - 2)

• y - 4 = 1/2( x - 2)

• y + 2 = 1/2( x - 4)

Write the equation in POINT SLOPE form:

( -5, -3); m = -1

• y + 3 = -( x + 5)
